"The Linksys KVM unit supports up to 1920 x 1440 Maximum Screen Resolution at an incredible 85Hz! I haven't seen another unit in this price range(or even units that are twice the price) offer a superior resolution and refresh rate. One of the most important features to look for in a KVM switch is keyboard and mouse emulation on both ports, which enables the user to boot into the opposing system's operating system without encountering any conflicts, an excellent feature to look for in any KVM unit you are considering for purchase."
